2 What we will cover How testing helps genealogy What is DNA? How do you select from the three testing companies? What to expect when you get your results Comparing matches to your genealogy research Contacting your new relatives

3 How DNA testing helps genealogy Confirm the work you have done Confirm suspected family relationships and find out if stories are true Break through brick walls Trace your surname [male] and maternal line [female] Determine if same surname men descend from a common patriarch [male] Identify different surname men related on the direct paternal line [male] Elise Friedman, Webinar: Relative Roots, 2011, Carol Bosworth, Checking Family Genealogy for Medical History, 2014, Family Tree DNA, 2016

4 Other DNA testing takeaways Determine your paternal and maternal haplogroups Determine % breakdown of your ethnic makeup Learn about ancient origins and migrations May help with adoption, donor, and heir research Identify family medical history Elise Friedman, Webinar: Relative Roots, 2011, Carol Bosworth, Checking Family Genealogy for Medical History, 2014, Family Tree DNA, 2016

18 Family Tree DNA Results Marker & Certificate Certificate mtdna Family Tree DNA certifies that a mitochondria DNA sample taken from Hope Nelson Tillman differs from the Cambridge Reference Sequence (CRS)* at the numbered positions indicated, by the presence of the bases designated A, C, G or T: Haplogroup K2b1a Sample # N30062 The letters designate the base that occurs at each of those positions in place of the entire CRS. These are distinctive of this sample and may be compared to other people to confirm or rule out common descent, providing genetic evidence of genealogical relationships.
